Controllability of Multi-Rate Networked Control Systems with Short Time Delay
Feedback control systems wherein the control loops are closed through a real-time network are called networked control systems. Multi-rate networked control systems mean the sampling rates of notes in networked control systems are not the same. The controllability of multi-rate networked control systems are investigated in this paper for the first time. Based on the mathematic model of multi-rate networked control systems with short time delay, some sufficient or necessary conditions for controllability of multi-rate networked control systems are got using stochastic systems approach.
